[0002] With the rapid development of new energy, competition is intensifying, and the demand and requirements for high-performance motors are constantly increasing. The material grades used are getting higher and higher, and the thickness is getting thinner and thinner. Especially when the material thickness is 0.25mm or less, the core stacking using traditional mechanical buckling, welding and other processes cannot meet the quality requirements; and if only loose-piece products are produced, the subsequent processes will be increased, resulting in low production efficiency, high production costs, and product quality cannot be guaranteed.

On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present invention and to enable the scope of the present invention to be fully communicated to those skilled in the art.

[0071] like Figures 1 to 8 As shown, an embodiment of the present invention provides a glue dispensing tool for a self-bonding motor core punching die, comprising: a workbench, the workbench comprising a work base 11; a stamping assembly, arranged on the work base 11; a stepping drive assembly, arranged in a movable groove of the work base 11; a glue dispensing assembly, arranged on the work base 11, the glue dispensing assembly is used to perform glue dispensing operations on core punching sheets; a stacking assembly 5, arranged in the work base 11, the stacking assembly 5 is used to perform stacking operations on core punching sheets; a second drive assembly, arranged on the work base 11.

[0072] In an embodiment of the present invention, by setting up a step-by-step driving component, the core punching sheet can pass through the stamping component step by step, so that when the core punching sheet reaches the glue dispensing process, the core punching sheet has been successively stamped with the tooth grooves, through holes and inner contours by the stamping dies of each stamping component; by setting up the glue dispensing component, the glue dispensing of the core punching sheet is more complete and comprehensive, while reducing the waste of glue dispensing; by setting up the stacking component 5, there will be no misalignment when the core punching sheet is stacked; by setting up the second driving component, the core punching sheet can easily reach the position of the core punching sheet stacking process after the glue dispensing is completed.

[0073] like Figure 1As shown, the workbench further includes: a side plate 12 disposed on the work base 11; and a stamping plate 13 disposed on the side plate 12.

[0074] In the embodiment of the present invention, the side plates 12 are arranged on both sides of the upper end of the working base 11 to support the stamping plate 13. A through groove is arranged in the middle of the stamping plate 13 to facilitate the die punching and glue dispensing processes on the stamping plate 13.

[0075] like Figure 1 As shown, the stamping assembly includes: a first U-shaped plate 21, which is arranged on the working base 11; a first cylinder 22, which is arranged at the lower end of the first U-shaped plate 21; and a punching module 23, which is connected to the output end of the first cylinder 22.

[0076] In the embodiment of the present invention, the first cylinder 22 is turned on to drive the punching module 23 to move downward to punch the core punching sheet on the punching plate 13 .

[0077] like Figure 6 As shown, the stepping drive assembly includes: a first fixed block 31, which is arranged at the lower end of the working base 11; a first motor 32, which is arranged on the working base 11; a first connecting rod 33, which is arranged on the output end of the first motor 32; a second connecting rod 34, which is hinged to the first connecting rod 33; a third connecting rod 35, which is hinged to the second connecting rod 34; a fourth connecting rod 36, which is hinged to the third connecting rod 35 and hinged to the second connecting rod 34; a limiting rod 37, which is hinged to the first connecting rod 33; a support plate 39, which is arranged on the third connecting rod 35; and a push block 38, which is arranged on the support plate 39.

[0078] In the embodiment of the present invention, the first motor 32 is turned on to rotate its output shaft, thereby driving the first connecting rod 33 to rotate, the first connecting rod 33 drives the second connecting rod 34 to rotate, the second connecting rod 34 drives the third connecting rod 35 and the fourth connecting rod 36 to rotate, and through the connecting rod movement of the first connecting rod 33, the second connecting rod 34, the third connecting rod 35 and the fourth connecting rod 36, the movement trajectory of the push block 38 is achieved to intermittently push the core punching sheet for a certain distance, and at the same time, after the core punching sheet is pushed to the next process, the push block 38 will return from the lower end of the core punching sheet, and after the stamping is completed, the core punching sheet will be pushed to the next process, and this is repeated, so as to realize the automation of the die; wherein the limit rod 37 is used to connect the first connecting rod 33 on the two sets of stepping drive components, so that the two sets of stepping drive components can run synchronously.

[0079] like Figure 7As shown, the glue dispensing assembly includes: a spiral groove plate 45, which is arranged on the working base 11; a second motor 46, which is arranged on the spiral groove plate 45; a second fixed block 41, which is fixedly connected to the output end of the second motor 46; an electric push rod 42, which is arranged on the second fixed block 41; a mounting block 43, which is fixedly connected to the output end of the electric push rod 42; a glue dispensing nozzle 44, which is arranged on the mounting block 43; a glue storage tank 47, which is arranged in the working base 11; a glue supply device 49, which is arranged on the glue storage tank 47; a glue supply hose 48, which is arranged on the glue supply device 49, and passes through the mounting block 43 to be connected to the glue dispensing nozzle 44.

[0080] In the embodiment of the present invention, the core punching sheet is pushed to the glue dispensing process by the push block 38. When the glue dispensing operation is performed, the second motor 46 is turned on to drive the second fixed block 41 to rotate, and the electric push rod 42 is turned on to drive the glue dispensing nozzle 44 to move inward. When dispensing glue, the second motor 46 and the electric push rod 42 are turned on at the same time, so that the glue dispensing nozzle 44 moves along the vortex groove of the vortex groove plate 45; at this time, the glue supply hose 48 follows the glue dispensing nozzle 44 to move in the vortex groove plate 45, and the glue dispensing nozzle 44 will glue in the shape of a spiral line. The glue is sprayed on the surface of the core punching sheet in a uniform shape, so that the glue spraying is more uniform; at the same time, the amount of glue sprayed is controlled by controlling the glue output of the glue supply device 49 to avoid excess glue affecting the quality of the core punching sheet and causing waste; wherein, the glue storage tank 47 can be manually inspected and glue can be replenished regularly; when the glue dispensing of one core punching sheet is completed, it is only necessary to reversely operate the second motor 46 and the electric push rod 42 to perform the glue dispensing operation on the next core punching sheet, and there is no need to return to the empty stroke, which is more convenient.

[0081] like Figure 5 As shown, the second driving assembly includes: a second U-shaped plate 61, which is arranged on the working base 11; a third fixed block 62, which is arranged on the second U-shaped plate 61; a third motor 63, which is arranged on the third fixed block 62; a threaded rod 64, which is rotatably connected to the third fixed block 62 and is arranged on the output shaft of the third motor 63; a threaded sleeve 65, which is threadedly connected to the threaded rod 64; a second telescopic rod 67, which is arranged on the threaded sleeve 65; a catalyst disc 68, which is arranged on the second telescopic rod 67; a suction cup 691, which is arranged on the catalyst disc 68; an air pump 66, which is arranged on the threaded sleeve 65; an exhaust hose 692, which is arranged on the air pump 66, and passes through the second telescopic rod 67 and the catalyst disc 68 to be connected to the suction cup 691.

[0082] In an embodiment of the present invention, during the glue dispensing process, the second telescopic rod 67 is moved downward. When it reaches a specified distance from the core punching sheet, the nozzle at the lower end of the catalyst disk 68 is turned on to spray the catalyst on the upper end of the core punching sheet. After the glue dispensing and catalyst spraying operations are completed, the air pump 66 is turned on to generate negative pressure inside and outside the suction cup 691 to adsorb the core punching sheet, and then the second telescopic rod 67 is started upward to lift the core punching sheet to a certain height; at this time, the third motor 63 is turned on to drive the threaded rod 64 to rotate, thereby driving the threaded sleeve 65 to move horizontally. When it moves to just above the stacking assembly 5, the air pump 66 is turned off to make the negative pressure inside and outside the suction cup 691 disappear, and the core punching sheet performs free fall motion and enters the stacking process; the third motor 63 is configured as a servo motor.

[0083] like Figure 3 As shown, the stacking assembly 5 includes: a second cylinder 51, which is arranged on the working base 11; a stacking disc 54, which is arranged on the output end of the second cylinder 51; a pressure sensor 55, which is arranged on the stacking disc 54; a first telescopic rod 52, which is arranged in the working base 11; a clamping arc plate 53, which is arranged on the output end of the first telescopic rod 52; and a drop hopper 56, which is arranged on the working base 11.

[0084] In the embodiment of the present invention, a through hole is opened on the working base 11, and the stacking assembly 5 is arranged in the through hole. When the core punching piece is in free fall, it will first pass through the drop hopper 56, enter the through hole, and fall on the stacking disc 54; the pressure sensor 55 is used to determine whether the core punching piece has reached the specific total number of stacked cores set. The total number of stacked cores means that a core rotor is formed by stacking several core punching pieces, and several core rotors are formed during one stacking operation; when the specified total number of stacking is reached, the pressure sensor 55 will transmit a signal to the controller, and the controller will control the extension of the first telescopic rod 52 to push the clamping arc plate 53 outward. Since the first telescopic rod 52 and the clamping arc plate 53 are provided in two groups, respectively on both sides of the stacking disc 54, when clamping, the two clamping arc plates 53 will clamp the core punching piece to the center position of the stacking disc 54, and make each layer of core punching pieces overlap and adhere to each other, so as to avoid the problem of individual core punching pieces protruding during stacking, thereby improving The quality of stacking is improved; wherein, a baffle is fixedly connected to the upper end of the clamping arc plate 53, and when the two clamping arc plates 53 are clamped, the baffle on the clamping arc plate 53 will form an arc-shaped baffle, which plays a blocking role in the subsequent stacking operation; during the dispensing operation, the dispensing device is controlled by the controller to set the lower end of the number of core punching sheets not to be subjected to the dispensing operation; the catalyst disk 68 is controlled by the controller to set the upper end of the number of core punching sheets not to be sprayed with the catalyst, thereby controlling the number of layers of the core rotor; during the stacking operation, when the pressure sensor 55 senses that the core punching sheets on the stacking disc 54 have reached the total number of stacked cores, the second cylinder 51 is turned on by the controller to drive the stacking disc 54 to move upward, and drive the core punching sheets to move upward, so that the top core punching sheet collides with the arc-shaped baffle, thereby completing the stacking operation. After the stacking is completed, it is only necessary to move the output end of the second cylinder 51 downward to take the stacked core rotor away from the working base 11.

[0085] like Figure 1 As shown, the punching assemblies are provided in three groups, and the punching modules 23 in the three groups of the punching assemblies are different.

[0086] In the embodiment of the present invention, three groups of stamping assemblies are used to stamp the tooth grooves, through holes and inner contours of the core punching sheets respectively, so the stamping modules 23 on the three groups of stamping assemblies are different.

[0087] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
